20w car audio amplifier based TDA 2004

This 20w car audio amplifier circuit described here offers a 20 watt booster that will allow you to realize the power amplifier with which one can increase the power output from the car stereo up to 20 Watts maximum. The input IN is connected to the output of the receiver, U output is connected to the speaker as shown on car audio amplifier scheme. It is very important to ensure that the speaker has no connection tothe chassis (ground) if not, the integrated circuit IC1, a TDA 2004 will Continue reading
